HI Neeraj.
Please ask your basis consultant to set the parameter with tcode rz10 as below.
icm/server_port_0 PROT=HTTP, PORT=8000, TIMEOUT=1000, PROCTIMEOUT=1200
icm/host_name_full stcdd.<domain_name>
and also maintain the host file entry for the server in your local machine C:\Windows\System32\drivers\etc\hosts.
